## Detailed Description

The **SoCoordinateElement** class is yet to be documented.

FIXME: write doc.

## Constructor & Destructor Documentation

### SoCoordinateElement::~SoCoordinateElement (void ) \[protected\], \[virtual\]

Destructor.

## Member Function Documentation

### SoType SoCoordinateElement::getClassTypeId (void ) \[static\]

This static method returns the **SoType** object associated with objects of this class.

### int SoCoordinateElement::getClassStackIndex (void ) \[static\]

This static method returns the state stack index for the class.

### void \* SoCoordinateElement::createInstance (void ) \[static\]

*This API member is considered internal to the library, as it is not likely to be of interest to the application programmer.*\

 Creates a new instance of the class type corresponding to the **SoType** object.

### void SoCoordinateElement::initClass (void ) \[static\]

Initialize relevant common data for all instances, like the type system.

### void SoCoordinateElement::init (SoState \* state) \[virtual\]

FIXME: write doc.

Reimplemented from **SoReplacedElement**.

### const SbVec3f \* SoCoordinateElement::getArrayPtr3 () const

Returns a pointer to the 3D coordinate array. Don't use this method unless **SoCoordinateElement::is3D()** returns TRUE.

This method is not part of the original SGI Open Inventor v2.1 API.

**Since**

Coin 1.0

### const SbVec4f \* SoCoordinateElement::getArrayPtr4 () const

Returns a pointer to the 4D coordinate array. Don't use this method unless **SoCoordinateElement::is3D()** returns FALSE.

This method is not part of the original SGI Open Inventor v2.1 API.

**Since**

Coin 1.0

### void SoCoordinateElement::print (FILE \* file) const \[virtual\]

FIXME: write doc.

Reimplemented from **SoReplacedElement**.
